Question

janice is roller - skating at a constant speed away from her house. the first half of the street is flat, but the second half has a steep upward hill. janice moves more slowly as she skates up the hill. which graph shows janices position as she roller skates away from her house?

Explanation:

Step1: Analyze flat - part motion

On the flat part of the street, Janice moves at a constant speed. In a position - time graph, a constant speed is represented by a straight - line with a constant slope.

Step2: Analyze hill - part motion

On the hill, she moves more slowly. A slower speed means a smaller slope in the position - time graph.

Step3: Identify the correct graph

The graph should have a steeper slope for the flat part (first half) and a shallower slope for the hill part (second half). Graph X shows this behavior as it has a steeper line for the first part and a less steep line for the second part.

Answer:

X.
